Electrochemical water splitting holds promise for producing clean hydrogen at industrial scales, but current technologies often falter under large current densities. Recent advances in catalyst design and scalable synthesis strategies are bridging this gap, offering materials that maintain high efficiency, stability, and durability under harsh operational conditions. This review synthesizes progress in scalable electrocatalyst production, from electrodeposition and corrosion engineering to thermal treatment approaches, and further to their combinations. By addressing the key challenges of performance degradation, bubble management, and cost limitations, the study highlights emerging solutions that can accelerate the industrial adoption of green hydrogen production technologies.
